Yin Yan discloses dealings in 2 companies, chiefly Bio Essence Corp and Marwynn Holdings, Inc. Between 6 June 2023 and 19 November 2025, the trades on record add up to 10 filings.

The open-market side counts 2 purchases for €4.7M alongside 8 sales for €2.3M. On balance, insiders were net buyers of €2.4M. Buying on the open market means paying the going price with one's own funds, a different act from receiving shares as pay. Since January 2026: no purchases and 3 sales on the market.

The latest filing, published on 14 October 2026, reports an open-market sale of €2,378 in Bio Essence Corp. The latest purchase dates back some time: it was published 737 days ago, on 11 October 2024. Sales are harder to read than purchases, since they often meet personal needs such as tax or diversification. This summary is built from SEC (Form 4) disclosures alone and does not predict where the share price will go.
